How can I pass a variable with anchor()

Hi guys!

I'm a newbie in codeigniter.
I'm trying to pass an information through anchor() function.

Here, I want to attach a variable 'id' that relates to that description and pass it to a controller named 'test'. In that controller I want to retrieve the variable from the URI and do something.
But where can i attach it?

echo anchor('test',$value->description,'');
